Going with Holset - Help with turbine housing

[604CruisinCroat]

Hi there I will be going with either an HX30 or HX40 with a twin scroll setup.

Just wanted to know who makes a divided turbine housing that will bolt on to these turbos?

Should I go t3 or t4?

A link to where I can get the housings would be excellent.

Thanks.

The majority of them come with twin scroll housings stock. As for going t3 or t4 thats up to you and your goals. I myself just finished up my HX40 t4 19cm/2 build and am loving it. The top end pulls all the way to redline and just never stops.

Not too sure about the hx30, but the hx35 from the Ram's, comes with a divided t3 housing off the bat. Most hx40s have divided t4 housings ranging from medium to huge.
What are your goals and intended use of the car?

What kind of spoolup are you seeing? Any logs?

toofast82, I hope to have some logs to post up soon. Working out a couple of kinks at the moment with some other stuff.

im sure every question has already been asked on this forum over the years, but does that mean people should stop making threads and asking them? I have searched but i want to be sure because i will be spending alot of money soon. Are the stock twin scroll housings good to use? Thanks.

Also I want to know which ones have the 8 blade billet wheel?

 

[toofast82]

The 8blade hx35 compressor wheel flows about 52lb/min while the 7blade flows around 60lb/min. Same goes for hx40, the 8blade compressor flows the least.

My friend works at Cummins and asked me for a part number for the turbo I want.

I tried looking it up, but there are SO MANY part numbers for the HX40

What I want is a 7 blade HX40 with a billet wheel, stock t4 twinscroll. Do the volvos have the billet wheel?

Can somebody help me with a part number?
